Section D: Large Array Frame with Extender Bars for Pick Points
The Large Array Frame with Extender Bars (Short or Long) can be used to provide additional pickup points for more extreme tilt angles.
For this application, attach the Extender Bars to the Large Array Frame before attaching any modules using the following steps:
1.
Use
RoomMatch™ Array Suspension Angle Calculator
software to determine the hole positions on the array frames for required
aiming angles and confirm array does not exceed load limits of frame.
2.
Locate the 2 extender bars noting the R (right) and L (left) markings on the labels.
3.
Locate the Large Array Frame and position on the ground near the intended suspension point.
4.
From the rear of the Large Array Frame, insert the bar marked L into the channel on the right side of the array frame. Note: the
double rows of mounting holes should be facing upward.
5.
Align the bolt holes with the intended position marker (OUT or IN) of the bar.
6.
Insert 4 bolts (2 per side) and finger tighten each until all bolts are installed.
7.
Tighten all 4 bolts with socket tool using torque of 35 to 40 foot-pounds (47 to 54 Newton-meters).
8.
Repeat steps 3 to 6 for the R bar into the channel on the left side of the array frame (Note: the
L
and
R
markings on the extender
bars assume viewing position in front of the array frame.)
With the Extender Bars now secured to the Large Array Frame, proceed to the steps outlined in Section A to continue constructing the
array.
